Fire class: When to use which fire extinguisher?

First of all: Not every fire extinguisher can be used for all types of fires. Decisive is on the one hand the fire class or the material that burns and on the other hand the extinguishing agent in the fire extinguisher. We show you which fire classes and types of fire extinguishers there are and when you should use which fire extinguisher.

It is best to use the carbon dioxide extinguisher (fire class B). Alternatively, foam extinguishers (fire class A and B) or ABC powder extinguishers (fire class ABC) would also work. The advantage of carbon dioxide is that surrounding electrical equipment is not damaged. Please do not pour water on electrical equipment!

ABC powder extinguishers (fire class A, B and C) work best, they are frost-proof and extinguish not only the gas stove, but also cable fires. However, they have the major disadvantage that the electronics or the engine can suffer great damage, because the powder settles into every little crack. Alternatively, the foam extinguisher (fire class A and B) would be possible, but not for the gas stove, but for the electronics in the camper without damaging surrounding equipment.

Preferably water extinguishers, alternatively also foam extinguishers. In principle, powder extinguishers (caution: danger of suffocation) or carbon dioxide extinguishers /CO2 extinguishers (caution: danger of frostbite) are also suitable. Never hold the hose of the fire extinguisher in the face, but start with the upper body. Any extinguisher is better than the fire blanket, please do not use it.⁽¹⁾

The basic rule is: personal protection before property protection. Do not put yourself or others in danger. Only extinguish if it is still a small fire. Once the fire is extinguished, remain at the danger point and, preferably with another full fire extinguisher, observe whether there is a renewed build-up of gluten or flames and repeat the extinguishing attempt until the fire department has arrived.
